Muscle modifications in fibromyalgic patients revealed by surface electromyography (SEMG) analysis

Table 2 Absolute basal (t = 0 secs) and final values (t = 30 secs) (mean ± SD) of MDF, CV and FI of FM patients and controls.

	MDF (μV) FM	CV (m/sec) FM	MDF (μV) controls	CV (m/sec) controls
Basal (t = 0 secs)	93.2* ± 6.0	4.0 ± 0.5	138.2* ± 5.1	5.1 ± 0.5
Final (t = 30 secs)	72.6 ± 3.9	3.1 ± 0.3	86.1 ± 2	3.4 ± 0.3
Fatigue Index	1.10*	0.89*	2.41*	1.66*

MDF: median spectral frequency; CV: conduction velocity
MDF and CV are expressed as absolute values. Mean ± SD of MDF, CV and FI are calculated
on 100 patients and 50 controls.
*Basal MDF controls vs basal MDF FM, p < 0.0001
*Fatigue Index controls (MDF and CV) vs Fatigue Index FM (MDF and CV), p < 0.0001
